This invention relates to disabling gas guns, of the type which discharge irritating and disabling gases, for example, of the 'tear gas type, especially adapted for use with a mechanical firing system.

An object of the invention is to provide a gun which will be positive in action and deliver a rapid and violent blow by the firing pin against the rimer of a' cartridge.

A further ob]ect is to provide a gun of the above type which contains a release mechanism, the release being actuated by the release of a spring controlled trigger, the trigger upon its release setting free a spring actuated firin pin.

A. further 0 ject is to provide a spring actuated gas gun containing a spring actuated trigger, the trigger being released by the release of a, tension wire, the trigger then setting free a spring controlled firing pin,

the latter delivering a sudden and powerful blow against a chemical gas charge containing cartridge. 1

Other objects of the invention will be apparent to those skilled in the art upon reading the specification.

Figs. 14 and 15 are side and front views respectively of a detachable movable ele- 7o of the type illustrated in Figs. 10 and 11;

and a Fig. 17 is a view in elevation of a firing pin of the type illustrated in Figs. 10 and 11. In Fig. 1, the gun is suitably detachably connected to a barrel 2 for example by screws 3, the upper end of the barrel is connected to a suitable fitting 4, shown as a broken pipe coupling which contains a suitable screen 5 to retain fragments of wedding, etc., generally used in the manufacture of-cartridges. The topof the pipe coupling 4 may be suitably closed for example by a nipple and cap 6, or by any other means. The discharge side of the ipe coupling 4 is provided with a duct, or example a nipple 7 which may pass through a partition 8 o a building or room, and to the outer end of the nipple 7 is secured a suitable nozzle 9, or other distributing device, provided with discharge ports or openings 10 to discharge the gas 11 into the area to be gassed.

The gun I may consist of a metal block 12 provided with an opening 13, Figs. 2 and 6, into which is detachably secured the barrel 2 by the screws 3; within the end of the barrel 2 is placed the cartridge 14, Figs. 6 and 7.

15, Fig. 6 within which is'a firing pin 16 actuated by the spring 17, the firing pin 16 is provided with a groove 18 having an inclined wall, and in the adjacent partition wall 19 is a hole 20 inwhich is placedthe movable element'shown as a ball 21, which latter engages the firing pin by the groove 18, the hole 20, being drilled from the edge. Extending from the bottom end of the gun 1 is a long chamber 22, with a threaded end 23, in which latter is placed the plug 24 provided with the hole 25. In the chamber 22 is inserted the trigger plunger 26 actuated by. the spring 27, the trigger being provided with a groove 28. In Fig. 6, the trigger 26 is shown as connected to the tension wire 31, which latter passes through the hole 25, the tension wire being connected to a. suitable control not shown which is a part of a mechanical discharge system; a pin 30 being used to temporarily hold the' trigger until the installation is completed.

To set the gun, the barrel 2 is removed, the firing pin 16 pushed down, and the trigger 26 pulled back until its upper surface is below the hole 20, and the ball 21 inserted into the hole 20 until it engages the groove 18 of the depressed firing pin; the trigger is then released sufiiciently for it to rest against the temporary pin 30 in the position shown in Fig. 6. The barrel 2 and the cartridge 14 are now attached, the pin 30 removed, and the gun is ready for firing. In the position shown in Fig. 6, the ball 21 rests against the straight portion of the wall of the trigger 26 and in the groove 18 of the firing pin, thereby securely locking the firing pin. The ten sion wire 31 leads to a control connected in a mechanical firing system not shown, and when the wire 31 is released, the spring 27 forces the trigger 26 to the position shown in Fig. 7, the inclined surface of the groove 18 in the firing pin forcing the ball 21 into the oove 28, releasing the firing pin which latter then Violently strikes the cartrid e 14, and fires the same. The discharge 0 gas, and wadding, etc., from the cartridge, passes through-the barrel 2 into the coupling 4, the wadding, etc., being caught and held by the screen 5 while the disabling and irritating gas passes through the nozzle 9, and out of the discharge ports 10, as blasts 11, Fig. 1.

Figs. 10 and 11 are modificationsnof a gas gun resembling in general the gun illustrated. in Figs. 6 and 7 respectively. In Figs. 10

and'11 the movable element 40 is attached by a light spring 41 to the plug 42, Figs. 14 and 15, the plug being detachably secured in the chamber 22 by the screw 43, Fig. 10. The movable element 40 shown as a plug fits loosely in the hole 20. The firing pin 45 is provided with a recess having an inclined surface 46, and the trigger 47 with the recess having an inclined surface 48; the two inclined surfaces extending in opposite directions.

assume To set the guns illustrated in this modification, the gun barrel and cartridge are removed, the firing pin 45 pressed down while the trigger 47 is at the top of the trigger chamber, Fig. 11. The plug 40 will spring into the recess of the firing pin against the inclined surface 46, Fig. 10. The trigger 47 is then retracted until its plane surface is opposite to the plug 40 and holds the latter against the firing pin as shown in F igJlO,

trigger is retracted, said means adapted to bedisengaged and cause the discharge of said pin when said trigger is released.
